I've never had problems with condenser mics. Granted, I've been doing voice acting and music recording for many years, so I understand the potential drawbacks. Still, I would rather have more editing to do in post and have great audio than use a dynamic mic and have (very slightly) diminished quality.
Qualifications for part D include having Part A, Part B and/or Part C. If I am eligible when does it become effective? Medicare becomes effective when you turn 65, the first day of that month. For example, if you turn 65 on October 20th, 2009 your Medicare coverage would have become effective October 1st, 2009. There are also general enrollment periods from January 1 to March 31 of each year. If you choose to enroll this way, coverage becomes effective on the first of July of the same year.
To enroll in Medicare coverage, qualifying individuals must apply for this insurance plan during the seven-month period that begins three months before the month they turn 65 and ends three months after the month they turn 65.
